Can (presuambly) crude oil "explode" if it's not mixed with air? It's been many years since I did chemistry but I have a vague recollection about "rapid exothermic" reactions requiring certain conditions, and crude oil in its thick gloopy liquid state definitely doesn't have that no matter how much oxygen you throw at it. It will just burn.
